Bunny :: NoFinalOctetError一段时间后没有消息

Question

使用安装了official docker image的兔子mq，我的工作人员在一段时间（大约40秒）后失败并出现Bunny :: NoFinalOctetError异常。

我的工作人员代码是：

require 'bunny'
require 'securerandom'

#TODO set host as parameter
rabbit_conn = Bunny.new
rabbit_conn.start

ch   = rabbit_conn.create_channel
q    = ch.queue("task", :durable => true)
ch.prefetch(1)

begin
  q.subscribe(:manual_ack => true, :block => true) do |delivery_info, properties, body|
        pp body 
    ch.ack(delivery_info.delivery_tag)
  end
rescue Interrupt => _
  rabbit_conn.close
end

我通过以下代码发送数据：

require "bunny"

conn = Bunny.new
conn.start

ch   = conn.create_channel
q    = ch.queue("task", :durable => true)

[
    'titi',
    'toto',
    'tata'
].each do |d|
    q.publish(d, :persistent => true)
end

sleep 1.0
conn.close

并且在40周年之后我得到了我的工作人员的以下输出

"titi"
"toto"
"tata"

有关网络的更新

我嗅到网络，因为它似乎是一个格式错误的网络数据包。实际上，错误是在收到特殊数据包后触发的。

下面的Whireshark捕获，在接收到数据包299时发生错误。

但我不知道这个数据包是什么，也不知道为什么它不是由兔子处理的。

原来是数据包解析的问题。

可以跟踪错误her
